Inventor: ITO YORIYASU
IPC: H04N1/41
Filed: 1993-12-01
Abstract: PURPOSE:To reduce a required time by providing a storage device storing received FAX data and printing out directly desired FAX data not via a host computer. CONSTITUTION:The printer interfaces a host computer (HCP) 101 via a host computer I/F section 102. A storage device 105 comprising a HD or the like stores FAX data received from a public line 114 via a FAX I/F 113. A data compression expansion section 108 expands received compressed FAX data into binary picture data and displays the data on a display device of the HCP 101. Furthermore, expanded picture data are stored in the storage device 105. The user selects desired reception data by the display device or a liquid crystal display operation panel 106 of the HCP 101 to command printing. A main control section 107 extracts desired reception data from the storage device 105 and uses a printer engine 112 to print out the data on a plain paper sheet.

Filed: 1987-11-30
Abstract: PURPOSE:To prevent an excessive current from flowing to a measuring device or the like in a withstand voltage test, by connecting a voltage charged to a cable final terminal to an earth circuit at a predetermined cycle in a DC loader for performing a DC withstand voltage test for a power cable or the like. CONSTITUTION:When a loading of a power is started, a potential at a cable final terminal 5A rises with the passage of time. Then, as a time measuring section 11 counts t1, a relay circuit 13 is actuated and a charge voltage at the cable final terminal 5A flows to an earth circuit 7 reducing the potential to about 0. After t2, the relay circuit 3 is opened automatically. By repeating the charging and discharging operation, the potential of the cable final terminal 5A is kept from reaching a dangerous voltage V0[V]. On the other hand, in case a leakage occurs in a cable 5 in a loaded section S1, a leakage signal I0 is detected to protect devices and simultaneously, abnormality is reported to outside with the action of a short-circuit alarm 8.

Abstract: PURPOSE:To improve the appearance on opening a hinged door, by providing a movable blade along the inside of the rear free end of one side hinged door and holding it so as to be freely rotatable through an arm and projecting the movable blade toward the other side hinged door when closing the door. CONSTITUTION:A hinged door 3 is closed, the rear end of extended part 4b of a movable blade 4 abuts on the movable blade guide 6 attached to the upper and lower part of a box body. Then the extended part 4b is pushed and the blade 4 rotates around the shaft 10, resisting against the torque of elastic means of a spring 9 or the like and it is pressed along the guide 6. Next, the arm 7b slants around the axis 8 and the blade 4 projects to the rear face of the other side hinged door 2 while being led by the guide 6. When the hinged door 3 is completely closed, the blade 4 closes the clearance between the free ends of the hinged doors 2, 3. Further at this time, the extended part 4b is formed by a blade end material 11. The thickness thereof is made about one third of the chief part of blade. In this way, the movable blade is prevented from extending in the free condition and the appearance can be improved. Further, it can be used for making an enclosed space.

Filed: 1989-11-21
Abstract: PURPOSE:To contrive a cost reduction by adjusting the various densities of output images by regulating an exposing speed and/or pressure developing speed in place of changing the light quantity of a lamp. CONSTITUTION:Microcapsule paper 15 is housed in a sag housing path 27 when the transporting speed of feed rollers 16c is lowered and the exposing speed is lowered while feed rollers 16d are held stopped. The sag is eliminated and the density of the output images decreases when the rollers 16d are started thereafter and when the images are pressure developed at a standard speed. The exposing speed increases and the microcapsule paper 15 is housed into the housing path 27 when the microcapsule paper 15 is transported by the rollers 16c at the speed lower than the speed of the rollers 16d while the rollers 16d transport the microcapsule paper 15 and color developing paper 18 and the pressure development is kept executed at the standard speed. The sag is eliminated and the output images darken when the rollers 16d are stated and the pressure development is executed after the exposing operation is stopped by stopping the rollers 1c upon ending of the exposing.

Abstract: PURPOSE:To prevent the generation of defects caused by resin burrs at every process after moldings, by adopting two-split structure of the upper die of a pair of mold dies for resin-sealed semiconductors consisting of the upper die and lower die, and providing an air vent between them. CONSTITUTION:The first upper die 9 and second upper die 10 constitute a set of upper dies, and a lead frame 6 with a semiconductor mounted is set in a cavity 4 beforehand. And, a resin tablet 2 has been heated up to a specified temperature, a plunger 1 applies pressure (p) to it, and it is pressed through a running gate section 3 into the cavity 4 made by the upper dies and lower die 8 heated up to a specified temperature.

Title: Self-temperature control heater
Inventor: HIRAI NOBUYUKI
IPC: H05B3/14
Filed: 1988-11-30
Abstract: PURPOSE:To detect heating of a heater at a temperature more than a melting point of crystallized resin used for a positive resistance temperature characteristic resistor and shut off power supplying thereto so as to prevent such as fire by composing the heater of the positive resistance temperature characteristic resistor in which conductive powder is dispersed in the crystallized resin, a pair of electrodes and a spring. CONSTITUTION:A heater comprises a positive resistance temperature characteristic resistor 1 in which conductive powder is dispersed in the crystallized resin, a pair of electrodes 2 and 3 formed unitedly with the resistor 1, an insulative cover 4 covering the positive resistance temperature characteristic resistor 1 and the pair of electrodes 2 and 3 and a spring 5 disposed between the insulative cover 4 and the pair of electrodes 2 and 3. Shape-life of the crystallized resin is loosed when a temperature of the resistor 1 increases higher than a melting point of the crystallized resin to be used due to heat applied to the resistor 1 from another heat source. Thus, the electrodes 2 and 3 touch with each other due to external force applied by the spring 5 to produce an excess current. The excess current is then detected by a circuit to shut off a voltage applied for self-temperature control. Therefore, fire and fuming are prevented.

Title: Method and circuit for temperature-depending reduction of oscillation parameters of oscillator
Inventor: PEETAA HAIMURITSUHERU
IPC: H03L1/02
Filed: 1988-11-30
Abstract: PURPOSE: To substantially improve the total temperature stability of an LC oscillation circuit by distributing a positive feedback path to two partial paths which are a 1st partial path with temperature dependence and a 2nd temperature-nondependent partial path capable of compensating temperature nondependent constant loss. CONSTITUTION: The positive feedback path includes the coupled partial paths K1 and K2 , and the partial path K1 compensates the loss of a 1st group by a temperature compensating method. In this case, energy for compensating the temperature-nondependent loss (2nd group) is coupled through the partial path K2 without temperature dependency. Namely, energy for the loss of a temperature coefficient which should be formed by superposition is coupled through the partial paths K1 and K2 according to a proper distribution. In case of a dielectric proximity switch, variable loss in a driving blade represented by a resistance Rm is compensated through variation of coupling by the coupled partial path K2 (Rm belongs to the 2nd group).
